Assmnons To Henman Specication e! Application nl ed January 3 4To 'all whom t may concern.'

-Be it known that We, and ARTHUR E. Bonson, citizens or' the .United States, residing at v Santa Barbara, in the `county of Santa. Barbara and State f Californian-have invented a certain new and usefulv Bra ke for Talking-Machines, of which the following is a specification.

This invention relates to automatic stop mechanism, and more Vparticularly to an au. tomatic stopmechanism especially designed fora talkingmachineg which ordinarily has arotating record support or'member and a reproducing member, as a, sound-box and tone-arm, said record member and reproducing member being rel latter beingl commonly fed relatiyelyto" the foner bythe coaction offthesoind-boxwith therecord grooyeffff?" 1 20 Heretofore'automatic stop mechanisms for talking-"machines have been devised 'Wl 1i c' h necessitated the manual manipulationof=1 Vsome adjustable element, in`"'o'rder' that the ystop mechanism .might become operative 4at a Y desired and predetermined point,-` in the op` eration ofthe machine, as at the completion of the" reproduction of the sound-record. Such manual manipulation of4 the adjustable element became necessary with each' diiferent record reproduced, because of the fact that different records Vterminate at diil'erent .dis' tances from the centers of the tabl-ets'. It is an object' ofthisin-ventionto entirely do away with theneces'sity `oi" any `manual may nipulation of parts of the mechanism, ingr;l der that the machine shall stnp-at'the desired time.

I tial or relative movement between these elements to cause the actuation of the stop mechanlsm. It will be apparent, however,

that the same operation may result upon a material variation in the speed of lateral movement of the reprodueing member such, forexainple, as a material decrease in the speed of such movement.

The invention is susceptible of embodilment in a variety of mechanical 'toi-ins, one

of whieh, for the purpose of illustration, has been selected and` described with con- Siderable particularity in the aeeoinpany/ ing description, but it is to be expressly understood that suoli eiilbodiment ol the invention for not deSlgned as a definition of the invention, reference being had tothe accompanying claims for this purpose.Y

tablet constituting a rotatingr momia-.1; Above and adapt/ed to eoiperate ivith the record tablet. is a reproducing member, shown as oonipri'sinp, the usual or any con ventional sound-box 4- communieatiimr with and carried by the usual tone-arm 5, which together constitute a traveling i'neniber. 'llie tone-arm is rotatably mounted in any usual or conventional way upon a/brai-.ket (3 in communication willi a. sound-aniplifier, as indicated in dotted lines in Fig. l, the reproduring member being,r normally progressed across the record tablet by the coaetion between the sound-box and the record groove.

Mounted upon the braeket in any desired or suitable way, is a supportingr ,meins ber 7, preferably in the form ol a. bent rod, rari-ying; at its upper' end the plate-like memllxtending through this table 8 at about tlie'i:eiiti 'al portion thereofis a pivot pin i). Mounted upon the table 8 and secured in pivotal relation therewithliy the pivot pin S) is the T-shaped supporting arm l() provided at its outer end with upturned ilanges 1l and' l2. The (lange l2 is provided at its upper edge with a horizontally extending ear 13 from which is supported inv susi'iended relation a 'headed pii'ot pin 14. 'The pivot pin 14 is secured in the earl in any Conventional way, as by serew-,

threaded engagement, a lock-nut 1.5 being providedto securely lock the pm in its proper position. Supported on the head of the pin 14: are two lished disk-sluiped meinvidini.: the projo-cling portion 2l) lior a pur pose hereinafter deserii-iid. Between the disk' 1G and the stop member 1f) is a. spring member 21 provided with arms which bear at theirouter extremities afa'iiist the dished portion of the disk 17, such spring member beiingi seim'rated from. the plate 17 at the center by a. washer. This spriinii,f member provides a frictionalfor yielding connection between the stop member 1i) and the brake element, whereby they' normally rotate as a unit but are capable of independent rotation.

Above the stop member 19,011 thepin 14, is mounted a worm 2Q provided with a flange 23, which may be ii'itegra with the worm, and which Vianize bea-.rs upon and rotates 'with the stop member 19. It is apparent that any desired means may be provided for tive relation with the record, it begins `t0 travel inwardly through the coaction of its usual needle with the record groove. Mov'o-" ment of the tonearm inwardly moves the rod 51, and thereby, through the extension 49, the plate-like member 47 is rotated about its pivot t), causing the eccentric pm 54 to move toward the central portion of the slot formed by the fork 55, permitting lever 56 to follow. The lirst result of this inovemcyt is that the arm 1() is permitted to be swung about its pivot l), through the force cxerted by thespring (i0, to bring the arm 1() and its .supported members into normal working relation vitith the turn-table,wliere by the brake eleiaifnt is brought into frictional'engagement with the periphery of the turn-table and thereupon begins to rotate, lug 39 being then held out of the path ol? projecting portion 20 by linger (32 bearing on cam surface 31u'. Rotation of the brake element produces` a rol ation of the worm 22 which, through wena-wheel 24, drives the threaded lneii'ibe; 25'. Threaded member 25 and its driving mechanism are so designed as to drive lever 27 approximately synchroiioiisly with the movement of the ai'm 41 by 4tone-arm 45, any i'lill'erence in speed being in favor of the arin 4l, so as to insure that the ialgefiif slot 45 shall beV held against the rc- 4dubed` extension of pin 46. When the threaded member begins to rotate, it lofls lever 27, and thereby pin 46, longitud v,

and arm' 41, which has been-hold sla..-i iiiziiy relatively to the lever 27'by engagement with the pin `l-l, with a re; .ltaiit slipping between a' 'n 40 and plate-hie member 47, now begins to keep pace with the pin 46, because the tone-'arm lends always to drive the arms 40 and 4l, through the fictional connection between arm '40 and plate-like member 47, at a.]iproxiiiiately the .same rate ol' movement and at least at as great a speed j as that at which it is advanced by the record .groo-ie.- The. `further moveii'ient of the tone- :arin v inwardly permits a 1urtlieiA swing :of 'the lever 56, whereby the iiiiger (32 is with-- drawn fro'iii engagement with, the cam surfaced-1S. 5e i'espoiidir Arm -35 with itsextension 37 is tl'i'ereby p n'i'itted to drop, and arm 41 is corpath ofthe projecting portion 20, as the arm 35 is over-weighted by the connecting 1iiernlber-34, whereby the gravity member 31 norn iiially swings about the rod '2(3 to maintain the lur 3l) elevated. As .tl-1e toiie-arm con- .h

new move 'as a unit, until the tone-erm ceases is to be expressly understo L y-l( \i\:i'ered:until the edge of slot .45 rests onI the shoulder 4G off pin 46.. The lug 3l) will not, l'iowever, fall into the t0 advance for any reason, as when it has reached the end of the record groove. Arm 41 thn also ceases further niovemeiit,'a`nd the brake element, being still in contact with and rotatedv by the turn-table, continues to drive the threaded member 25, whereby the lever 27 is further advanced and shoulder IG is withdrawn from under the edge of the slot 45. 'lhereiipon arm 41 falls through gravity, its linger 44 engaging the inger 80 and raising the tooth 28 out of contact with the threaded member 25, and its lug 43 pressing down upon the extension 37 and overcoming the weight of the member 31, whereby the lug 39 is for'ced down into .thc path of the projecting portion 20`0f the rotary stop member 1S), stopping further rotation of this member. Thereupon thcnrotary brake element immediately produces a retardiiig and braking action upon the turntable, the frictional connection between the brake element and the stop member 19 permitting a slight slipping between the brake element and the stop member, until the turntable, and thereby the motor, is brought to a stop, the provision of this frictioiial connection preventing injurious jars. 4 i

lt will be apparent that a material variation in the speed of advance of the toIie-arm, such as a material. decrease in its speed of advance, will similarly decrease the speed of advance of the arm 41, whereby pin 46 with its shoulder 4G will bc advanced out. from under the edge of the slot 45 to cause the actuation of' the-L brake element as above de-v scribed. It will also beapparent from the above delaileddeseriptioii that a stop mecha` nism has been provided whichis controlled by the movement. of the'tone-arm without the necessity of prior manual manipulation of adjustable parts, and which operates'iinmedia tel y upon the cessation of movement of the tone-arm to effect the stopping of the While the preferred embodiment has been described with considerable artieula-rity, it

:that sur-n einbodimciit is for purposes of illustration only, that-the invention is's'usceptible of'a variety of mechanical expressions, some of which will readily suggest themselves `to those skilled in the art, andltliat'snch einbodi ment is notintendcd as asliinitatlion of the sco )e of the invention, reference being had-to t e appendedclanns as 'a definition of the scope thereof.
